(FR) SYSTÈME ET PROCÉDÉ DE ZONAGE AXIAL D'ÉNERGIE DE CHAUFFAGE
Abstract
(EN)
A heater system (20) for an exhaust system (18) is provided. The heater system (20) includes a heater (28) disposed in an exhaust conduit (32). The heater (28) includes a plurality of heating elements (38) disposed in the exhaust conduit (32). A heating control module (30) controls the plurality of heating elements (38) differently according to operating conditions specific to each heating element (38). In other forms, the heater system (20) for an exhaust system (18) has a plurality of heating zones, instead of a plurality of heating elements (38). The heating control module (30) controls the plurality of heating zones differently according to operating conditions specific to each heating zone.

L'invention concerne un système de chauffage (20) pour un système d'échappement (18). Le système de chauffage (20) comprend un appareil de chauffage (28) disposé dans un conduit d'échappement (32). L'appareil de chauffage (28) comprend une pluralité d'éléments chauffants (38) disposés dans le conduit d'échappement (32). Un module de commande de chauffage (30) commande différemment la pluralité d'éléments chauffants (38) selon des conditions de fonctionnement spécifiques de chaque élément chauffant (38). Dans d'autres formes, le système de chauffage (20) pour un système d'échappement (18) comporte une pluralité de zones de chauffage, au lieu d'une pluralité d'éléments chauffants (38). Le module de commande de chauffage (30) commande la pluralité de zones de chauffage différemment selon des conditions de fonctionnement spécifiques de chaque zone de chauffage.
